The Design Of The Shoe

1. finished product graph analysis
As shown in figure 2-2-14, this is a typical kind of shoes. Its predecessor is like a shallow shoe, and its back is like a whole tongue shoe. The shallow bar rises up in the middle of the shoe, forming a "rat tail". Take this rat tail as a turning point and connect it with the ordinary back gang.

The features of the shallow surround shoes introduced above are narrow and long, and the rear ends of the shoes are wider, breaking the inherent pattern of the shallow weevil and forming their own unique style. The so-called "Xi Li Shi shoes" is a variety of shallow leather shoes, if the tail line of the rat tail is flatted horizontally, it is a whole tongue type shallow shoe.

Pay attention to its processing technology, the tongue and shoe mouth adopts the technology along the mouth, because there is only one broken line between the tongue and the back, and the small horse part is inserted behind.

There are many changes in this detail, all of which belong to the changes of the shoes of the West. Because of the translation of the "Si Li Shi" as a drug, the name of the shoe is only spread in Wenzhou, but this innovative spirit that breaks the traditional structure is still worth learning.

(1) last type selection of shallow enclosure shoe last.
(2) the structure is similar to the structure of the tongue shaped shallow shoe, and the design method is similar.
(3) the components include a shallow web, a tongue cover, a rear heel, a horse head, a rubber band, and six pieces of seven pieces along the mouthpiece.
(4) a small horse head, a pony head pressure rubber band, a back pack and a rear end of the pressing strip are inserted into the shoe cover and the surrounding strip.
(5) special requirements do not leave a distance between the tongue and the broken line of the back, and there is a natural amount of deformation when it is stretched.
The width of rat tail is between 10 and 12mm.

2. structure design drawing
See the picture of the structure of the 2-2-15.

(1) design the tongue tongue length of the tongue and shoe contour line at E'and take about OO'= 25mm. Design the tongue from the E'point to the O' point.
Design rubber band and horse head parts underneath the tongue. Follow the small horse head parts to design the shoe outline, and make the difference between the inside and outside. The distance from the tongue of the tongue to 10 to 12mm is a parallel line separating the tail of the mouse.

(2) design the shoe cover and the fence strip to use the arc to intersect with the EV extension line, find the J2 point, make the length difference J2J2', then supplement the 1/3 difference. Draw the outline of the shoe cover with the copy board on the straight line in the back, then connect it to the control line of the mouse tail. Add a 1 / 3 difference from the J'point. Draw the outer outline of the fence with the replica board on the back curve, and connect it to the control line of the mouse tail. The position of the two line coincides with the O. Then design the mouse tail contour.
Imitate the outline design of the outside, and draw the outline. The front end of the fence is trimmed. Finally, the contour of the bottom rib and the difference between inside and outside are designed.

(3) draw the basic template of the template as shown in figure 2-2-16.

There are also many changes in the shape of the shoes. See 2-2-17.

As shown in figure 2-2-17, this is a structural sketch of three different kinds of shoes of the island. But it can be seen that their common feature is the clever combination of shallow structure and ordinary gang.
(a) a mouse tail is formed on the shallow section and combined with the back of the elastic opening.
Figure (b) uses the break line to combine with the dark rubber band.
Figure (c) borrows the shape of rat tail and combines with the rubber band.
All kinds of shallow surround shoes are the variant design of ordinary cover shoes. If there is a problem, we must distinguish between the design of the foundation structure or the design of the shoe cover, and find out the causes of the problem, and find the way to solve the problem.
